I agree that Adele has been manipulating everyone but i do think people on these forums are being a bit unfair!
You have 12 (or in this case 14) people go into a house for 10 weeks of their life (potentially) to win £70K or, what they really want, which is celebrity. They don't go in there to make 12 new mates. So yes, Adele is being all things to all people, is making sophie's life miserable and is generally using Jade to do most of the dirty work, but why should she behave differently? the only reason i can think of is because she's risking public hatred of her (although it never did Nick any harm once he was out) and so will not win. However the most famous HMs of the past have been those who've stayed in longest so adele is not nec. being stupid my going for the 'no nomination' route.
Sophie meanwhile should stick up for herself - she's going to get nominated anyway (she must know this) and so should just tell them to f**k off. As people have pointed out more than once, they're all adults in there (even Jade!) and should take responsibility for what goes on there. It's true that not everyone can see what we see in terms of Adele's machinations, but isn't that what life's about? isn't that why we enjoy BB anyway? because for the only time in our lives we can see everything and find out what's going on behind other people's backs? it gives us control of the situation in a way we can never have in our own lives. Personally, i love BB and i often wonder how i would cope in the BB house but ultimately i think everyone in the house must be slight psychotic to contemplate 10 weeks without people you can trust, books to read, knowledge of what's going on in the outside world, freedom etc... i think you ultimately actually have to be pretty self-obsessed to find the idea of living in the BB house at all attractive and i think that most of the HMs in there this time are just that. so we shouldn't be surprised that many of them seem so 'shallow'.
Anyway, these are just my thoughts on the whole thing - it's easy to become really involved in the HMs and their lives while watching BB but i think it's so easy to take hatred of the people inside too far... i am sure people will disagree with me and feel free to! just wanted to add my piece i guess...
